1. The importance of keeping blood sugar stable

Keeping blood sugar stable plays a key role in preventing or slowing the development of diabetes as well as its complications.
According to a study by the American Diabetes Association, a safe blood sugar level for diabetics is:
Before meals: 90 - 130 mg/dL (5.0 - 7.2 mmol/L). 1-2 hours after a meal: less than 180 mg/dL (10 mmol/L). Before going to bed: 110 – 150 mg/dL (6.0 – 8.3 mmol/L).

2.1. Hypoglycemia Hypoglycemia can be explained when blood sugar levels drop below a safe level, not enough to supply the body to function. Hypoglycemia often occurs in people with diabetes due to complications in the treatment of the disease. When hypoglycemia occurs, the organs in the body do not have enough energy, causing the activities to stall.
Although it is still possible to maintain activities through energy obtained from some other sources such as proteins and lipids, this is only temporary. On the other hand, hypoglycemia seriously affects the functioning of cells and red blood cells, two parts that depend entirely on the energy provided by glucose. Therefore, hypoglycemia needs to be detected and treated promptly, if prolonged, it can lead to complications that cause severe brain damage, even death.
2.2. Hyperglycemia Hyperglycemia is a condition when blood sugar levels are too high, and if there is no timely treatment, there is a high possibility of damage to important parts of the body such as the heart. , kidneys, eyes or nerves. In particular, diabetic ketoacidosis and hyperosmolar syndrome are evaluated as the two most serious complications caused by hyperglycemia.
Ketosis occurs due to high blood glucose levels, the body does not have enough insulin to function, so it mobilizes energy by breaking down the fat structure, causing the formation of waste products, also known as waste products. are ketones. The excessive accumulation of ketones will cause acute complications of ketoacidosis. Ketosis is common in people with type 1 diabetes, causing the patient's body to become dehydrated, even confused, and not clear in the mind.
Hyperosmotic syndrome, which occurs when sugar levels exceed 600mg/dl (33 mmol/l), is common in people with type 2 diabetes. This syndrome makes it impossible for the body to use it. Sugar, when entering the body, is immediately eliminated through urination. People with hyperosmolar syndrome often urinate often, causing severe dehydration, in addition, they may show symptoms of convulsions, loss of vision, hallucinations.
